Toilet paper

Each nation has its own way of approaching toiletry. The countries of the Middle East did not invent anything at all - they simply wiped themselves with their left hand. For Muslims, the left hand is considered dirty, so it was used for such things. Against this background, it is interesting that rich people in other countries used wool, and the poor - any improvised accessories. The stick with a fixed sponge was considered the most common for a long time.

More than 30 billion toilet paper rolls are used worldwide every year. This means that by the time you have read this subheading to the end, another 6000 rolls will have been used up - one thousand every second.
